flying buttress in Culture

flying buttress

An external, arched support for the wall of a church or other building. Flying buttresses were used in many Gothic cathedrals (see also cathedral); they enabled builders to put up very tall but comparatively thin stone walls, so that much of the wall space could be filled with stained-glass windows. The cathedrals of Chartres and Notre Dame de Paris were built with flying buttresses.
